The Speed of Light and Gravity
We all know that light travels fast – 299,792,458 meters per second, to be precise. Still, if the sun were to suddenly disappear into a mysterious void, you and I on Earth would not notice for about 8 minutes and 20 seconds. Or would we? Would we not immediately feel the sudden jolt of ourContinue reading “The Speed of Light and Gravity” Continue reading

Another thing to share: I love when I’mContinue reading “The Beginning: A Little More of Me” Continue reading

My knowledge of astronomy, and the universe in general, was very limited because of this. Like most people I had a basic understanding of … Continue reading Astronomy and Religion → Continue reading

The Moons of Jupiter
Source: New Moons The Solar System is home to four giant gaseous planets named Jupiter, Saturn, Neptune, and Uranus. These gas giants have many satellites due to their mass and subsequent gravitational pull. Jupiter is the largest planet in the solar system and has fascinated humans for hundreds of years due to the large amount … Continue reading The Moons of Jupiter → Continue reading
